deps: update asyncpg requirement from >=0.31.0 to >=0.32.0

[dependabot]

Updates the requirements on asyncpg to permit the latest version.

Release notes

Sourced from asyncpg's releases.

v0.32.0

Improvements

• Support Python 3.15 (#1367, #1378) (by @​elprans in 1b118464 and 58c0c595)

• Support PostgreSQL 19 (#1379) (by @​elprans in 8d2a5aed)

• Make pool min_size a maintained connection floor and add init_size to control the number of connections opened at startup (#1323). Idle connections at or below min_size are retained, and closed connections are replaced in the background. init_size defaults to min_size. To preserve the previous behavior, where the pool could drain to zero, replace min_size=N with init_size=N, min_size=0. (by @​shatilov-diman in 67a1cbc5)

• Use hashlib.pbkdf2_hmac() for faster SCRAM password derivation (#1359) (by @​twelfthlabor in 00319a9b)

• Use the statement cache for copy_records_to_table() introspection (#1360) (by @​matemax in dd058652)

Fixes

• Clean up connections rejected by target_session_attrs immediately so an unresponsive rejected host cannot delay the selected connection, and cleanup tasks cannot outlive the event loop. Rejected connections are aborted without waiting for a graceful disconnect; servers may log "unexpected EOF on client connection" if the Terminate message is not delivered before the transport closes.

• Fix a connection pool deadlock when releasing a connection after a protocol abort (#1324) (by @​pchaseh in 4a83cc2f)

• Honor Connection.close(timeout=...) while waiting for a pending cancellation (#1361) (by @​gyanu2507 in c06bcb4d)

• Prevent stuck cancellation from blocking connection teardown or pool release by bounding cancellation with the command or release timeout (#1370) (by @​elprans in 4cf02203)

• Preserve the server error when the connection closes mid-operation (#1369) (by @​RitiGrover in 6c8f1a7a)

• Fix COPY cleanup when a records generator raises, preserving the original exception and avoiding protocol desynchronization and stalled rollback (#1358) (by @​CodingCossack in fdc6bc8f)
